Chapter 5. Using feature gates in a hosted cluster
You can use feature gates in a hosted cluster to enable features that are not part of the default set of features. You can enable the TechPreviewNoUpgrade feature set by using feature gates in your hosted cluster.
5.1. Enabling feature sets by using feature gates
You can enable the TechPreviewNoUpgrade feature set in a hosted cluster by editing the HostedCluster custom resource (CR) with the OpenShift CLI.

-
You installed the OpenShift CLI (
oc).
Procedure
Open the
HostedClusterCR for editing on the hosting cluster by running the following command:$ oc edit <hosted_cluster_name> -n <hosted_cluster_namespace>
Define the feature set by entering a value in the
featureSetfield. For example:apiVersion: hypershift.openshift.io/v1beta1 kind: HostedCluster metadata: name: <hosted_cluster_name> 1 namespace: <hosted_cluster_namespace> 2 spec: configuration: featureGate: featureSet: TechPreviewNoUpgrade 3
WarningEnabling the
TechPreviewNoUpgradefeature set on your cluster cannot be undone and prevents minor version updates. This feature set allows you to enable these Technology Preview features on test clusters, where you can fully test them. Do not enable this feature set on production clusters.- Save the file to apply the changes.

TechPreviewNoUpgradefeature gate is enabled in your hosted cluster by running the following command:$ oc get featuregate cluster -o yaml
